Had one of the original Dysons for years and apart from the odd blockage, worked like a dream (inc dog hair) for several years; I left it as a present for the purchasers of my old flat.
When I moved to a new flat, I bought a powerful (2kw+) Hoover: they have been making 'em for around seventy years so I thought that they might have learned a thing or two; how wrong can one be? the thing is not even 'fit for purpose' in my opinion and when I complained, I got the usual ..... "you need to clean the filters" ***!
I'd go back to Dyson anytime; in fact, when I can afford it, I will.
